           Summary: cp/decl.c:1178  asserts if class "iterator" defined in a
                    subclass with wrapped multimap
           Product: gcc
           Version: 3.3.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: ervan at tharas dot com
                CC: gcc-bugs at gcc dot gnu dot org

When compiling under g++ 3.3.1 on Solaris or g++ 3.2.2 on x86 Red Hat 7.x
the following program causes g++ to assert as listed in the verbose output. 
Note that naming the inner class "iterator" is critical to producing the
failure.

This message contains:
1) The unpreprocessed source for reference
2) the -v output

This "Description" edit box won't accept the preprocessed output due to length
and the bug description form has no obvious option for attaching source. 
Regardless, it's the standard "map" header distributed with gcc 3.2.2 that is
being used.  Please advise if I can send the preprocessed output some other way.

#include <map>
using namespace std;
struct base {
    class iterator { };
};
struct mymap : public base {
    class map_wrap : public multimap<int, int> 
    { }; 
    class iterator { };
};
